H6: medical device problem code 2017 - failure to follow steps/instructions.A visual, dimensional, and functional inspection was performed on the returned device.The reported deflation problem was not confirmed.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no similar incidents from this lot.The investigation determined the reported deflation problem appears to be related to the use error.Factors that may contribute to deflation problems include, but are not limited to, deflation technique, contrast concentration, contamination in the inflation lumen, damage to the guide wire and/or inflation lumen.It was reported that negative pressure was applied for 15 seconds to deflate the balloon, but the balloon would only partially deflate.It should be noted that the xience skypoint, everolimus eluting coronary stent system, electronic instructions for use (ifu) specifies: deflate the balloon by pulling negative on the inflation device.Larger and longer balloons will take more time (up to 30 seconds) to deflate than smaller and shorter balloons.Confirm balloon deflation under fluoroscopy and wait 10 ¿ 15 seconds longer.In this case, it is likely the balloon was not allowed sufficient time to deflate before an attempt was made to remove the device, resulting in the reported deflation problem.There is no indication of a product quality issue with respect to manufacture, design, or labeling.
